The 10k pot is designed to connect to an analogue 0-10V control signal from a EC fan or VSD being used to control an AC fan.
The resistance of the potentiometer is 10k and it has a linear curve (ie the resistance at 10% is 1k, 50% is 5k, 75% if 7.5k, etc).
Please note the “0V” is to be connected to the 0V or GND terminal of the EC motor/VSD, not the Earth.
WARNING
The 10k pot and on/off switch is only for use with a 0-10V control signal and digital enable signals – do NOT connect it in anyway with a the 240V/415V power source of the fan or VSD.
